BLA-NK FOR AND METHOD OF MAKING BUTTON-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 367,010 dated July 19,1887.

Ap lieation filed November-29, 1886.

To all 2 071 072 it may concern:

. Be it known that I, FRANCIS H. RICHARDS, a citizen of the UnitedStates, residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented certain new and useful Improvements inBlanks for and Methods of Making Button-Fasteners, of which thefollowing is a specification.

This invention relates to improvements in methods of making and blanksfor one-prong button-fasteners, especially of the class de scribed in myapplication, Serial N o. 170, 4.47 filed July 2, 1885, as hereinaftermore fully set forth.

In the drawings accompanying and forming a part of this specification,Figure 1 shows a metallic wire which is supposed to have been divided upinto a series of blanks. Fig. 2 shows one of saidblanks. Figs. 3 and 4illustrate successive steps in the conversion of the blank into thecomplete Tshaped button-fastener shown in Fig. 5. Fig.6 shows a modifiedform of blank. Fig. 7 shows a fastener made from this form of blank.

Similar characters designate like parts in all the figures.

The single blank (designated in a general way by B) comprises a prong.2, and two headforming portions, 3 and 4.. These latter parts are formedby dividing on line 5 a continuation of suitable length of prong-2. Theblank being thus prepared, the two parts 3 and 4.

Serial No. 220,117. (No model.)

thereof are each bent first outward, as in Fig. 3, then further bentabout midway of its length, as shown in Fig. 4, and finally foldedtogether, as in Fig. 5. The prong 2 may be left in its original shape,or, if preferred, submitted to reshaping operations. The blanks beingprepared from the wire by dividing up this as illustrated in Fig. 1, allof the metal is utilized, and this Whether the blank be of the formshown in Fig. 2 or of that shown in Fig. 6. By using the first form theends of parts 3 and at meet at 6, in line with the prong; but with thesecond form said ends meet at 7, at one side of the prong. The form incross-section of the wire may be round or otherwise, as may bepreferred.

Having thus described my invention, I claim- 1. The improvement in theart of making one-prong button-fasteners from wire, consisting individing one end of a blank piece of wire into two head-forming portionsand folding each of said portions to form the respective ends of thefastener-head, substantially as set forth.

2. The blank B for a button-fastener, the same being divided at one endinto two headforming portions, substantially as set forth.

FRANCIS H. RICHARDS.
